IMPROVEMENT IN STEAM-RADIATORS.

Specification forming part of Letters Patent No. 101,668, dated April 5,1870.

To all whom it may concern Be it known that I, JosEPH SnAcKLE'i ON, ofRahway, in the county of Union, State of New Jersey, have inventedcertain new and .useful Improvements in Steam-Radiators;

' a top view of the radiator.

A represents the base of the radiator, which ismade of sheet metal ofthe proper thickness, and the top and bottom plates aremade from asingle piece or sheet, and the sides and ends are also of sheet-metal,and in one or more pieces, as may be convenient. The base is divided,transversely or otherwise, into two chambers, B and (J, by apartition-wall, a, (indicated by dotted line b, Fig. 3,) a portion ofthe side of the base being broken away to show the partition-wall.

The top plate of the base is perforated to receive therectangular-formed pipes D in as many places as desired, and in the holefor each pipe a screw-thread is cut, so that one end of pipe D will beover the inductionchamber 0 and the other end over the oppositechamberB. The pipes D form a rectangle, and the uprightparts of said pipes arescrewed into the top plate of the base firmly and securely, while thetop ends are screwed into the right-angled pieces that form the angle,and the top or.horizontal piece is finished with a right and left handscrew-thread, and

tofit in and screw into the angle-pieces at the top ends of the twoupright pieces, and thus form the connection between the two chambers Band (l.

E is the induction-pipe, through which the steam is admitted into 0,thence going through pipes D into chamber B. F and G are eduction oroutlet pipes, having the proper stop or guage cocks, by which thesuperabundant and condensed steam is allowed to pass out of each chamberas may be desired.

'means for counteracting the unequal expansion of the pipe and the topand bottom plates of the base, caused by admitting the hot steam in atone side, which will always expand the side at which the steam is soadmitted, and cause the top and bottom plates of the base to break atthe curved ends of the central opening, and also in expanding the sideof the base where the steam is admitted it curves out the side, carryingwith it the bottom of the bent connecting-pipes. They being in acontinuous piece are apt to crack at the'upper and central part of thecurve, or

they will be torn asunder from the base plate, as they are not securedby going through the plate, and in either case causing a leak of steamand rendering the radiator worthless, while with the construction hereinshown and described, of having no central opening in the base, and byhaving the top and bottom plates whole, and having the pipes in piecesand the several parts screwed together and to the top plate of the base,will give sufficient elasticity to the pipe to stand the little unequalexpansion of parts, without breaking, cracking, or in any way causing aleak of the steam, either in the pipes, at their joints, or where theyare connected to the top plate. Nor can the top or bottom plate beliable to crack apartby the cause that operates to destroy the radiatorsthat have a central opening in the base, as mine is made of a singleplate and cannot well be broken by any strain that could be applied byan ordinary steam-heater, but if, by any means, any of the pipes shouldbecome broken or useless, any pipe or part of the pipe can be taken outby unscrewing the top or horizontal part first, and then either of theuprights can be unscrewed from the top plate, when another can be put inits place at small cost. Notso with the U-shaped pipes, for whenanybreak or crack is made in them the whole pipe is worthless, and an entirnew one must be had to replace it.

The steam-radiator herein described, having the top and bottom plates ofthe base, without a central opening, and the connecting-pipes D formedin pieces and screwed together and to the top plate of the base, in themanner and for the purpose set forth.
